Sure why not. From the SacBee:
The UC Davis physics undergraduate has reaped international attention since March, when The Bee wrote about his campaign to establish a new, scientifically accepted prefix, “hella,” to be used in front of units of weight, distance or just about anything.
It would be used much the same as kilo, mega and giga.
However, instead of designating, respectively, a thousand, million or billion, hella would mean 1027, or 1 followed by 27 zeroes.
Which, is like, totally a lot. According to anyone from Southern California, anyways. I can’t wait for the day when I can pop onto Newegg and buy a 1 hellabyte drive for my computer. [via]
